5 Claims.

This invention relates to a charting or recording device, particularlyadapted to be used in checking the parts of a motor vehicle or othermechanism requiring lubrication.

It is well understood that in order that a motor vehicle may operate inthe most efiicient manner it is necessary that certain parts belubricated at predetermined time intervals. As the driver of a motorvehicle usually leaves it at a service station for this purpose (whileattending to other business) he has no knowledge of how well the job hasbeen done, for the reason that the attendant often overlooks or fails tolubricate all the necessary parts, either due to unfamiliarity with thearrangement of such parts or because of neglect. Although the attendantmay fully understand the arrangement of parts to be lubricated, he oftenstarts lubricating parts which will cause his hands to become greasy andoily, then lubricates the parts which require clean handling, such asdoor hinges, knobs, etc. Such procedure usually results in the body orthe interior of the car becoming soiled with grease or oil.

It is therefore an object of the present invention to provide a chartingdevice which will enable the attendant of a service station to quicklylocate in sequence the parts of a motor vehicle which requirelubrication so that none will be overlooked.

Another object is to provide a charting device of the Characterdesoribed, including a charting strip and means for perforating thesame, so that the owner or driver of the machine, by referring to theperforated strip may determine whether or not his car has beencompletely lubricated.

'Other objects and advantages will be apparent from the followingdescription, reference being had to the accompanying drawing, in which:

Fig. 1 is a perspective view of the charting device.

Fig. 2 is a front elevation showing the straps applied theretosupporting the same on a person's body.

Fig. 3 is an enlarged Vertical section taken through the punch.

Fig. 4 is a section taken on line 4-4 of Fig. 3.

Fig. 5 is a section taken on line 5-5 of Fig. 3.

Fig. 6 is a top plan view with the cover or top i plate opened.

' is preferably formed from Sheet metal stampings.

Casing 10 consists of an upper portion or chamber 12 in which ismountedthe perforating or recording mechanism, and depending from theChamber is pocket 14, that serves to receive charting strip designatedat S.

Arranged in upper portion 12 of the casing is a horizontally disposedguide plate 13 that slidably supports the charting strip, the platehaving downwardly curved ends 16 and side flanges 18, which fiangesengage and are secured to the side walls 19 of the casing by screws orrivets designated at 20.

Charting strip S is folded in zig-zag formation and has printed orotherwise formed thereon indicia or characters designated at I (see Fig.7), .o

which may illustrate, for example, various parts of a motor vehicle thatshould be lubricated at predetermined intervals.

One end of charting strip S is adapted to be passed over plate 13 andconnected to a roller 21 that serves to move the strip across said plateso that the characters thereon may be successively observed, the rollerhaving a longitudinal kerf or groove 22 formed therein through itslength to receive the end of the strip, also to permit its removal aftersaid strip has been wound thereon.

Roller 21 is removably mounted in diagonally disposed recesses 23 formedin side walls of the casing and is held in place against shifting bygrooves 24 formed adjacent each end thereof that engage the lower endsof the recesses, the roller being provided with a knurled head 25tofacilitate turning of the same.

Slidably mounted in aligned openings 26 and 27 respectively formed inthe wall 29 of the upper portion of the casing and a guide block 30secured to one of the flanges 19 is a push pin 32 which serves toperforate and thereby form a record on the charting strip.

Pin 32 is provided with a reduced diameter portion 33 that is arrangedto pass into the opening 34 of a die 35 disposed directly above block30, and formed on the lower end of the pin is a button 35', andencircling said pin between block 30 and a shoulder 36 formed thereon 1.

is an expansion coil spring 37 which serves to hold the pin clear of thestrip.

Hingedly connected as indicated at 38 to the casing is a cover 40 (whichserves to protect the strip) having an opening 41 formed in its top endthereof is a suitable latch 45 which is arranged to engage a keeper orlug 46 formed on the end wall 47 of the casing, the latch being securedto and operated by a suitable handle 48.

Secured to the top of the cover is a spring tensioning device 49 thatengages the strip when the cover is closed. Secured to the side wall ofthe casing and engaging the end face of the roller is another springtensioning device 51 which coacts with the aforesaid device to hold thestrip taut on the plate. The cover is provded with fianges 50 whichengage the side walls of the casing, and formed in said flanges aresemicircular recesses (not shown) which engage the grooves in the rollerand thereby hold it in place within the recesses formed in the casingwhen said cover is closed.

From the foregoing it will be apparent that by turning roller 21, thenpressing on push pin 32, the strip may be perforated at intervalsthroughout its length.

Referring to Fig. 7, the indicia I printed on strip S includesillustrations of the various parts of a motor vehicle requiringlubrication and accompanying directions designated at D indicating whereand how often suchparts should be lubricated.

It is to be understood that the illustrations above referred to -arearranged in proper sequence so that attendants will start in lubricatingthe parts which will not cause their hands to become greasy.

The `charting device is adapted to be carried lby the attendant whilelubrcating the machine and is provided with a neck strap 52 and waiststrap 53Vfor this purpose, as clearly shown in Fig. 2.

In operation, the attendant first -refers to the -illustration appearingthrough the opening in the casing, and lubricates the parts thusindicated. He then .presses button 35 which perforates the stripadjacent the illustration. Roller 21 is 'then turned to bring thesucceeding illusvtration into view and the above operation repeateduntil all Vparts of the machine have been lubricated.

After lubricating the :parts and recording such `Operations in themanner above referred to, the

strip 'which is then wound on the vroller is adaptcd to be removed fromthe casing. This may be easily'done by openingjcover'l), lifting rollerV21 -out `of the recesses 123, 'and -removing the strip therefrom. Theroller may then be returned to the casing for another operation.

From the foregoing it will be apparent that the charting device not onlyprovides means Whereby an accurate record indicating whether a machinehas been completely lubricated may be obtained, but materially aids theattendant While performing such operation.

I claim:

1. A charting device comprising a casing having a sight opening formedtherein for the re- `ception of a folded charting strip havingcharacters formed thereon, a strip winding roll for connection With oneend of the charting strip removably mounted in said casing, and meansfor making a record on said strip.

2. A charting device comprising a casing for the reception of a foldedcharting strip, a strip Winding roll for connection with one end of saidstrip and removably mounted in said casing, and means for making arecord on said strip.

3. A charting device comprising a casing for the reception of aremovable charting strip having characters formed thereon, a coverhaving a sight opening formed in its top wall hingedly connected to saidcasing, means for supporting the charting strip within said casing, astrip winding roll for connection with one end of said strip andremovably mounted in said casing, means for making a record on saidstrip, means fengaging the strip for tensioning the same, and vothertensioning means secured to `said casing engaging said roll for holdingsaid strip taut on said plate.

'4. A charting device comprising a casing having a sight opening formedtherein for the recep- .tionof a folded removable charting strip having'characters ,formed thereon, ,a strip winding vroll -removably mountedinsaid casing for actuating .said strip, 'said roll having `alongitudinal groove formed therein throughout its'length for con-;necting vone .end of the strip thereto'and to .permit of itsremovalafter the same has been wound thereon.
